Device management network with support for roaming

ABSTRACT

A device management network that supports roaming selectively conducts device management activities on a mobile device when it is roaming. The mobile device is capable of determining that it is roaming and communicating the information to the DM server in order to allow the DM server to execute an operator specified policy (or policies) to determine if device management activities need to be conducted when the device is roaming. Later, when the mobile device is no longer roaming, but back in the home network, then the mobile device communicates another message to the DM server to inform it (or other servers that need to know) that the mobile device is no longer roaming. In another embodiment, the DM server is capable of detecting that the mobile device is roaming and acts according to policies.

BACKGROUND OF THE INVENTION

Electronic devices, such as mobile phones and personal digital assistants (PDA's), often contain firmware and application software that are either provided by the manufacturers of the electronic devices, by telecommunication carriers, or by third parties. If firmware or firmware components are to be changed in electronic devices, it is often very tricky to update the firmware components. Device management of electronic devices (such as mobile handsets) in an operator's network provides the means by which problems with a mobile handset can be diagnosed and fixed using firmware updates. However, if a mobile phone is not in the home network, conducting device management will often incur extra charges, due to the inclusion of roaming charges. A subscriber is not likely to be happy if the addition of roaming charges is likely to make device management expensive, if not prohibitive.

It is often difficult to determine what is wrong with a device when a problem is encountered. This conducting device management to determine what is wrong with the device, especially when the device is “roaming”, i.e. incurring roaming charges, is likely to make the subscriber, or an operator, unhappy. Conducting any device management is likely to be expensive when a user is roaming, especially if they involve downloading large files or transferring a lot of information, etc.

Server side solutions in an operator's network generally do not support anything to do with roaming. Similarly, the OMA DM based devices generally do not provide any indication that they are roaming, either to a user or to the DM server. Thus, there is no “roaming sensitivity” in device management solutions, in general.

Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with the present invention as set forth in the remainder of the present application with reference to the drawings.

BRIEF SUMMARY OF THE INVENTION

A device, system and/or method supporting roaming sensitivity for device management operations on electronic devices, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims.

These and other advantages and novel features of the present invention, as well as details of an illustrated embodiment thereof will be more fully understood from the following description and drawings.

DETAILED DESCRIPTION OF THE INVENTION

Aspects of the present invention relate to the configuration, management and updating of configuration parameters, firmware and/or software in a mobile electronic device that is capable of roaming. More specifically, aspects of the present invention relate to incorporating roaming sensitivity in device management, for example not initiating firmware updates if a mobile electronic device is determined to be currently roaming. Although the present application refers frequently to an electronic device in terms of a cellular phone, a pager, a personal digital assistant, or a personal computer, this does not represent a specific limitation of the present invention. A mobile electronic device for the purposes of the present application may comprise a wide variety of electronic devices having updatable code and/or configuration parameters that may be managed via a wired or wireless communications link using a device client resident in the electronic device. Although the following makes reference to the Open Mobile Alliance (OMA) protocols and specifications, representative embodiments the present invention may be applied in combination with other industry standard protocols.

FIG. 1 is a perspective block diagram of a device management network 105 that is capable of supporting roaming by selectively conducting device management activities when a mobile device is roaming. Device management on a mobile device is conducted on the mobile device by the device management network based on a roaming policy.

The device management network 105 is capable of conducting device management activities, such as firmware updates, software updates etc., in order to fix problems in the mobile device or to upgrade the mobile device. The device management network 105 comprises a device management (DM) server 109, a customer care server 157, an interface to network services 151, the mobile device 107 and a provisioning server 129. The mobile device 107 is capable of updating an application software 127, an operating system (OS) 119, or a firmware 117 in the mobile device 107 employing an update package delivered by the DM server 109 or a download server in the network. It is also capable of receiving provisioning information from the customer care server 157 or the provisioning server 129 to fix configuration problems or reconfigure software and hardware, even if the mobile device is determined to be roaming.

The mobile device 107 is capable of applying updates using one or more update agents 115 that are each capable of processing update packages or subsets thereof. The mobile device 107 is capable of receiving update packages, content of different kinds, configuration parameters, etc. It comprises the update agent(s) 115 that is capable of updating the mobile device 107, a roaming sensitivity client 125 that facilitates determination of “roaming” when the device is roaming, and a provisioning client 123 used to conduct bootstrap provisioning and continuous provisioning.

The mobile device 107 also comprises a DM client 163 that is capable of interacting with the provisioning client 123, the roaming sensitivity client 125, and other clients in the device, such as a diagnostic client and a traps client. The DM client 163 typically received DM commands from the DM server 109 and implements them, even if the device is roaming, unless the operator has a policy that prohibits management tasks while the device is roaming, or a user instructs the device (or the DM server) to not conduct management sessions while the device is determined to be roaming.

In one embodiment, the mobile device is capable of determining that it is roaming and communicating the information to the DM server in order to allow the DM server to execute an operator specified policy (or policies) to determine if device management activities need to be conducted when the device is roaming. Later, when the mobile device is no longer roaming, but back in the home network, then the mobile device communicates another message to the DM server to inform it (or other servers that need to know) that the mobile device is no longer roaming.

In another embodiment, the mobile device is not capable of determining that it is roaming and cannot communicate such information to the DM server. The DM server, or some other server in an operator's network, determines that the mobile device is roaming. In order to allow the DM server to execute an operator specified policy (or policies) to determine if device management activities need to be conducted when the device is roaming, the DM server or the some other server communicates information regarding roaming, such as a device roaming event (with the roaming network information) to the DM server. Based on such events received, the DM server can track the device if necessary, and also determine if device management should be conducted with the device based on the roaming network currently involved, and also based on the urgency of conducting the DM activity. The DM server is also capable of buffering up (i.e. queuing up) device management activities that have been deferred for a roaming mobile device, until the device gets back to the home network, or until the activities time out or are no longer deemed necessary.

In yet another embodiment, the mobile device is capable of determining that it is roaming and is able to communicate such information to the DM server. In addition, the mobile network is also capable of determining that it the mobile device is roaming and it communicates such information to the DM server. The DM server (or some other server associated with the DM server) tracks the roaming status of the mobile device, and, based on the operator's policies, as determined by policies maintained by the DM server (or a policy server associated with the DM server) defers some or all device management tasks that need to be conducted on the device that is currently roaming. Management tasks are deferred for the duration of “roaming”. When the user's mobile device is detected to have come back to the home network (default network), the deferred management tasks are automatically conducted. In a related embodiment, the user's approval is solicited before conducting the deferred management tasks. In another related embodiment, the user/subscriber with the device in a “roaming network” is prompted (for some management tasks, such as firmware update or software download) with an appropriate message indicating the need to conduct a management task and the user's approval is solicited. For example, a message such as, “Do you want to conduct a management task while roaming”? is displayed, prompting the user to select “Yes” or “No”. Based on user input, the associated management tasks are selectively conducted.

In a different embodiment, neither the mobile device nor the operator's network is capable of determining that the mobile device is roaming. When the DM server initiates a session with the DM client in the mobile device, it retrieves a network identification from the device. It then compares the retrieved network identification with a reference network id associated with the operator's network to determine if the mobile device is currently “roaming”. If it is determined to be roaming, then the DM server defers the management task, after aborting or otherwise terminating the current session. If it is determined that the mobile device is currently not roaming, then the management session is continued until it is completed or terminated. In a related embodiment, the user's approval is solicited before conducting a management task while the device is detected to be “roaming”.

In a different embodiment, if the network operator needs to update millions of mobile devices to fix a known bug (say with all devices of a make, model and version), it will be very expensive to fix bugs in the mobile devices that are roaming, especially if the operator has to bear the roaming charges. Thus, the operator needs to determine which mobile devices are not roaming and conduct management operations (such as fixing bugs) on those—the DM server facilitates both the determination of which mobile devices are not roaming, such as by retrieving a network id from the device, or by retrieving the information from a network server in the operator's network by means of a web services interface provided for that purpose. For those mobile devices determined to be currently roaming, the DM server defers the management operations, and queues them up for subsequent invocation, when the associated mobile device is determined to be not roaming.

In general, the device management network 105 supports roaming selectively and conducts device management activities on a mobile device 107 when the mobile device 107 is roaming. In one embodiment, the mobile device 107 is capable of determining that it is roaming and communicating the information to the DM server in order to allow the DM server to execute an operator specified policy (or policies) to determine if device management activities need to be conducted when the mobile device 107 is roaming. Later, when the mobile device 107 is no longer roaming, but back in the home network, then the mobile device communicates another message to the DM server to inform it (or other servers that need to know) that the mobile device 107 is no longer roaming. In another related embodiment, the DM server is capable of detecting that the mobile device 107 is roaming and acts according to policies specified by the operator (or the user).

The present invention provides for checking a policy (at least one) of the operator, if one exists, to determine if a management operation can be started when the mobile device is roaming. It also provides for prompting the user for authorization to conduct the management operation, if a policy of the operator does not exists, to determine if a management operation can be started while the device is roaming. Management operations comprise of firmware updates, configuration changes, continuous provisioning, software component download and installation and diagnostics and monitoring.

Accordingly, the present invention may be realized in hardware, software, or a combination of hardware and software. The present invention may be realized in a centralized fashion in at least one computer system, or in a distributed fashion where different elements are spread across several interconnected computer systems. Any kind of computer system or other apparatus adapted for carrying out the methods described herein is suited.
